[mac] SparkleSetup: support @2x images

Browse source 
Since the plugin images come from a manifest
with full paths, to support @2x images we have
to do a little more work by rebuilding the image
path based on NSWindow.BackingScaleFactor.

Theoretically this is forward compatible with
future scalings (e.g. @3x, @9000x).
